<p>PURPOSE:To specify a terminal by a keyword code string and to freely close a power source in a remote terminal from a host device by adding a remote power source enter function to a circuit adapter. CONSTITUTION:The titled device is a remote power source closing device installed on the circuit adapter 2 connected to the host device 21, and has a circuit control part 2 connected to a transmission line 11, a terminal connection part 3 connected to the terminal equipment 22, a code detection part 4 to detect a specific code string encoded by the circuit control part 2, and a power source control part 5 which is operated by the code detection part 4 and controls a terminal equipment power source 23. The code string encoded by the circuit control part 2 is also transmitted to the code detection part 4. With a call code string, etc., as a keyword in terms of transmission procedure, the code detection part 4 detects the code string, and when it detects the specific code string, it closes the power source of the terminal equipment power source 23 through the power source control part 5. Since the power source of the circuit adapter 1 is independently supplied from the terminal equipment power source 23, the circuit adapter 1 always supervises the code string outputted by the host device.</p> |
